1. Material untuk printing / main subtrate 2. Material untuk barrier 3. Material untuk heat seal 4. Material untuk melekatkan material - material di atas termasuk adhesive MATERIAL UNTUK PRINTING ( MATERIAL UTAMA ) Untuk proses cetak diperlukan material dengan sifat - sifat : - Mudah menyerap / menerima tinta - Permukaan cukup halus dan rata - Tahan terhadap perlakuan pada mesin cetak Contoh material untuk printing : Kertas, Cellophane, NY, PET, OPP SIFAT PELINDUNG (BARRIER) MATERIAL PLASTIK Semua material, kecuali kaca dan metal, bisa dilalui (permeable) oleh uap air, udara dan gas-gas lainnya Karena metal foil tidak transparan dan kaca tidak flexible untuk flexible packaging umumnya digunakan bahan plastik (polymer) Pengaruh uap air dan oksigen terhadap makanan : - Potato Chips

Uap air melempem Uap air bau tengik - Makanan berlemak Uap air - Kopi bubuk berjamur MEKANISME PERMEASI GAS MELALUI FILM TIPIS Tahap I : Gas melarut dalam film Tahap II : Gas terdifusi melalui film Tahap III : Gas keluar dari film ke tempat yang baru KONDISI TES YANG UMUM DIGUNAKAN 1. Jungle room
